当运行一个动作时，Sprite Kit会崩溃，或者仅在iPad Air和iPad mini上加载video
我收到来自Retina mini和iPad Air设备的崩溃报告，但不是iPhone 5S。 它出现在SpriteKit中，当有人点击一个应该在屏幕上显示另一个的精灵时。
我不能在非A7设备上重现这一点，所以想知道是否有人可以看看下面的崩溃日志，让我知道崩溃可能是由什么造成的？

if ([touchedSprite.name isEqualToString:@"Sad"]) { // Create the crop node if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) { cropNode.position = CGPointMake(touchedSprite.position.x - 120, CGRectGetMinY(self.view.frame)); } else cropNode.position = CGPointMake(touchedSprite.position.x - 120 * IPHONERATIO, CGRectGetMinY(self.view.frame) - 20); SKSpriteNode *sadSprite = [SKSpriteNode spriteNodeWithTexture:[SKTexture textureWithImageNamed:@"SadSprite"]]; [sadSprite setName:@"sadSprite"]; [cropNode addChild:sadSprite]; sadSprite.position = CGPointMake(sadSprite.position.x, sadSprite.position.y + sadSprite.size.height / 2); SKSpriteNode *maskedImage = [SKSpriteNode spriteNodeWithTexture:[SKTexture textureWithImageNamed:@"SadSpriteMask"]]; [cropNode setMaskNode:maskedImage]; [self addChild:cropNode]; NSArray *slurpSounds = @[@"sadSprite01.caf", @"sadSprite02.caf", @"sadSprite03.caf"]; // Keep the sadSprite in the same position in relation to the egg [sadSprite runAction:[SKAction moveByX:0 y:-sadSprite.size.height duration:0.6]]; // Move the sadSprite into position [cropNode runAction:[SKAction moveByX:0 y:sadSprite.size.height duration:0.6] completion:^{ [cropNode runAction:[SKAction playSoundFileNamed:slurpSounds[self.toolSoundNumber] waitForCompletion:YES] completion:^{ [sadSprite runAction:[SKAction moveByX:0 y:sadSprite.size.height duration:0.6] completion:^{ [sadSprite removeFromParent]; }]; [cropNode runAction:[SKAction moveByX:0 y:-sadSprite.size.height duration:0.6] completion:^{ [cropNode removeFromParent]; }]; }]; }]; }
谢谢。
经过一些试验和错误，我跟踪了这一切，其中的顶部，底部，左侧或右侧的片大小为0.我会说这是iOS上的一个错误。 尝试添加更多的填充图像，以便您的切片不会触及边缘。
